Reference design for wireless optical comms
A new technology from Texas Instruments dramatically cuts the cost and complexity of bringing the high-speed datarates of optical networking to end users.
The AC7 IVD provides DSL equipment manufacturers with a flexible design architecture by combining the AC7 central office chipset and narrowband POTS voice functionality with TI's Telogy Software for voice over packet (VoP) technology.
This new platform allows service providers to quickly deploy IVD line cards in DSLAM, DLC and MDU applications to easily upgrade their large installed base of POTS subscribers for DSL service.
TI's AC7 IVD platform uses Wintegra's high-performance WinPath access packet processor for VoP, DSL and IP multicast traffic aggregation and data management.

Advanced TDMA technology to boost cable bandwidth
Texas Instruments has unveiled its new technology featuring end-to-end advanced TDMA that will enable a 50% increase in upstream plant capacity.
Both VoP and packet aggregation capabilities can be provided as addon modules.
The line interface for POTS is managed by Legerity's subscriber line interface circuit (SLIC) and subscriber line audio-processing circuit (SLAC) technology, providing fully programmable transmission and loop supervision parameters.
"TI has been committed to DSL development since the industry's inception and our latest advancements in silicon and software demonstrate that we understand the needs of carriers looking to offer the most advanced DSL and voice services", said Greg Jones, General Manager of TI's DSL business unit.
"As more offerings become available via DSL, and the integration of voice and data becomes an essential requirement for today's competitive equipment vendors, TI aims to stay ahead of the technology curve through the continued development of products that will recognise the full potential of DSL coverage".
The AC7 IVD solution's lead customer is Fujitsu Telecommunications Europe, where it is used in the company's access gateway platforms for residential and business service.
Fujitsu's integrated voice line card subsystem provides ADSL and voice from a single unit providing V5, ATM BLES or H.248 options for signalling.
"Our Geostream access gateway solution was designed to meet the needs of carriers migrating their networks to NGN whilst supporting legacy services and backhaul", said Andy Stevenson, General Manager, Fujitsu Telecommunications Europe.
"TI's AC7 IVD easily integrates into our designs and offers unmatched performance and density for voice and data in a single unit".
TI's AC7 IVD supports industry-leading ADSL standards ADSL1, ADSL2 and ADSL2+.
For packet voice processing the IVD platform supports G.711, G.729AB, as well as a wide range of other low-bitrate codecs.
Telephony signalling protocol and conversion to and from the packet network signalling protocols, such as SIP, H.323 (IP), Megaco or MGCP are efficiently run on the Winpath processor.
AC7 performance is fully tested and proven via TI's interOps Test Labs, streamlining provider qualification and decreasing time-to-market.
TI's AC7 IVD is currently design-in with lead customers with general availability in Q1 2005.
